Application filed October 2, 1925. Serial No. 60,106.

The object of my invention is to improve.

the construction of the carriage and drying frame, to provide means for holding taught the perforated plate, and to provide a protecting edge for the plate, as fully described hereafter.

In the accompanying drawings:

Fig. 1 is a side view of a carriage and drying frame mounted thereon'located within the drying chamber of a drier, and illustrating my invention;

Fig. 2 is a sectional 2-2, Fig. 1;

Fig. 3 is an enlarged View of a detail of Fig. 1, showing the protecting edge for the perforated plate and the adjustable holding means for the plate;

Figure 4 is a sectional plan view on the line -44, Fig. 3; V

Fig. 5 is a perspective view of a portion of the perforated plate; Fig. 6 is a detached perspective view of the edging strip for the plate;

plan view on the line Fig. 7 is a detached perspective view of one of the clamp blocks;

Fig. 8 is adetached perspective view of one of the adjusting screw-bolts for the plate; and

Figs. 9 and 10 are detached views of one of the corner brackets of the carriage.

The casing 1 of the drier may be made in any manner desired. In this type of drier there is a series of guide rails 2 at the bottom of the drier. These rails have deep flanges, which guide and hold thecarriages and their frames against lateral movement.

, The upper rails 3-3" are spaced apart and support the carriage 4. Rollers 5--5 on the carriage travel on the rails as shown in Fig. 1. The rails 3 are located within the upper portion of the drying chamber 1, and the rails 3 arelocated outside the drying chamber and support the outer ends of the carriages as they are withdrawn from the drying chamber.

Each carriage has an inner vertical mem her 6 and an outer vertical member 7, con nected at top and bottom respectively by horizontal members 8 and 9. The members 8 and 9 carry the rollers 5 and 5 respectively. The members of the carriage are tubular in cross-section.

Angle brackets 10, shaped as shown in Figs. 1, 9 and 10, are located at the four corners of each carriage and are securely attached to the tubular members of the carriage by bolts or other fastenings. The brackets have lugs 11 on each face, which engage the tubular members 678 and 9 of the frame, and are attached to the members by bolts 12 as shown.

The bracket 13, for the trunnion 14 of the frame 15, is secured to the vertical member 6 in thesame manner as the brackets 10, Fig. 1. The bracket 16, for the trunnion 17, is attached to the vertical member 7 by bolts, as shown in Fig. 1. y

This construction makes a very substantial carriage, and as the members 7 are always outside of the drier, they can be used as handholds for moving the carriage into and out of the drier.

The drying frame 15 is made of a tube, bent at the corners. The ends of the tube are preferably connected to form a continu: ous rectangular tubular frame. At the front end of the frame is a plate 18, which is flanged at each side. This plate is of such width as to close the space occupied by the carriage'when the carriage is within the drying chamber.

. The skins to be dried are secured by suitable toggles 19 to a perforated plate 20. The perforations in the plate are close together, as shown in Figs. 3 and 5, The edges of the plateare turned in, as at 21, Fig. 5, and a reinforcing and protecting strip 22is attached to each edge of the plate, as shown in Figs. 3 and 4. a This strip 22 is bent into U-form and the edges 23 and 24 are bent to produce smooth edges. The edge 23 extends between the turned in portion and the body of the plate, as shown in Fig. 4. The plates are punched and then cut to size, leaving a raw edge, but by turning the edges in as shown, and applying a reinforcing strip, a smooth edge is provided. In order to secure the plate to the frame 15 and to holdthe plate taut, a series of clamp blocks 25 are secured to the edges of the frame. Each block is slotted at 26 to pass over the reinforcing strip, and is held to the strip and plate by screws 27. The blocks have threaded openings, and bolts 28 pass through openings in the tubular frame 15 and 1nto the threaded openings in the blocks.

On each bolt is a nut 29 for locking the bolt after adjustment. By this means, the plate can be drawn taut, and when necessary can be readily removed from the frame. The plate may be provided with one or more reinforcing strips 30, as shown in Fig. 1.

The frame can be turned on its trunnions from a vertical position to a horizontal position, with either side uppermost, so that the skins can be readily attached to the drying frame.

A chain 31, attached at one end to the carriage and at the other end to the frame, limits the movement of the frame in either direction.

The above described construction of drying frame and carriage is very substantial. The frame will allow the plate tobe held under tension at all times.

The frame is comparatively light and can be readily turned on its trunnions, and the carriage can be moved into and out of the drying chamber with very little effort.

I claim:

1. The combination of a carriage adapted to be inserted into a drier; aframe pivotally mounted on the carriage; a perforated nlate carried by the frame; and adjustable means for holding the plate to the frame.

2. The combination of a rectangular carriage made of a series of tubular members; brackets at the corners of the frame spanning the tubular members; and means for attaching the members to the brackets.

3. The combination of a rectangular carriage made of a series of tubular members; means at the corners of the frame to secure the members together, the vertical members of the frame extending above the upper horizontal member; rollers on the two vertical members arranged to travel on an overhead rail; and a pivoted drying frame mounted on the carriage.

4. The combination of a. carria to be inserted into a drier; a rame pivotall mounted on the carriage; a perforate plate within the frame for supporting the material to be dried; and adjustable bolts connecting the plate with the frame so that tension can be applied to the perforated plate.

5. The combination of a carriage; a frame pivotally mounted on' the carriage, said frame being made from a continuous tube bent at the corners; a perforated plate carried by the frame; clamp blocks secured to the plate at intervals; and adjustable bolts extending through the tubular frame and into the clamp blocks.

6. The combination of a carriage; a frame pivotally mounted on the carriage; a perforated plate located within the frame, the edges of the plate being turned in and a protecting strip attached to the edge of the plate, said strip enclosing the rough edge;

e adapted and means for holding the plate to the.

frame.

7. The combination of a frame; a. perfo rated plate within the frame and arranged to carry the material to be dried, the rough edges of the plate being turned in, with strips of material at the edges of the platehaving their edges turned in, one of the edges extending between the body of the perforated plate and its turned in edge; and means for securing the plate and strip to the frame.

8. The combination of a frame for a drier; 'a perforated plate within the frame having inturned edges; strips enclosing the inturned edges; clamp blocks secured to the edges of the frame and to the strips, each block being slotted to pass over the strip;

means extending through the strip, plate and block, said block having a threaded opening; and screw-bolts extending through the frame and into the blocks, so that the plate can be drawn taut.
